The present study explored the effects of sodium benzoate (SB), relocation, and storage time on the quality of sugarcane silage. The experiments followed a completely randomized design with a 2 × 4 × 2 factorial arrangement and four replicates. The treatments were as follows: (i) with (SB+) or without (SB−) SB (2 g∙kg⁻¹ on a fresh matter basis); (ii) with (R) or without (R0) relocation for 12, 48, and 72 h (R12, R48, and R72, respectively); and (iii) storage for 10 or 60 days after relocation. SB− silage showed a lower (p < 0.05) dry matter loss (DML = 155 g·kg⁻¹) without relocation (R0). SB+ silage showed the highest (p < 0.05) DML (257 g·kg⁻¹) with R72. SB use reduced (p < 0.05) the yeast count in silage that was stored for 10 days (SB+: 4.63 CFU·g⁻¹; SB−: 5.58 CFU·g⁻¹). The yeast count was higher (p < 0.05) in silage that was stored for 10 days after relocation, regardless of the relocation time. SB use increased the aerobic stability of silage after 10 days of storage. Thus, SB application is effective for the inhibition of yeast in relocated sugarcane silage. We recommend the use of SB when silage is relocated for 12 h and stored for 60 days after relocation.

This study aimed to determine the effects of relocation time (RT; Experiment 1) and storage time after relocation (ST; Experiment 2) on microbial population, fermentative characteristics, and chemical composition of corn silage. In experiment 1, corn silage was stored for 30 d, subjected to different RT (0–60 h), and stored again for 30 d. Thirty experimental silos were used in a completely randomized design, with three replicates per treatment. In experiment 2, after 150 d of ensiling, silage was [...] ABSTRACT This study aimed to determine the effects of relocation time (RT; Experiment 1) and storage time after relocation (ST; Experiment 2) on microbial population, fermentative characteristics, and chemical composition of corn silage.

We aimed to evaluate the effects of storage condition (SC) and storage time (ST) on the fermentative parameters and nutritional value of relocated whole-plant corn silage (WPCS) in plastic bags. A completely randomized design was used in a 2 × 5 factorial arrangement, with two SC (in the field without cover and in a barn as covered space) and five ST (10, 30, 60, 90, and 120 d), with four replications.

The current study evaluated the impact of aerobic exposure time (ET) and microbial inoculants (MI) on the fermentative and microbiological characteristics and the nutritional value of relocated whole-plant corn silage (WPCS). Treatments were arranged in a 4 × 5 factorial design: microbial inoculants (without inoculant (WI); L. plantarum (DSM3676; DSM3677) + L. buchneri (DSM13573) (LPLB); L. plantarum (MA18/5U) + P. acidipropionici (MA26/4U) (LPPA); and L. buchneri (DSM13573) (LB)) and non-relocated (NR) or relocated after 12, 24, 48, and 60 [...] ABSTRACT The current study evaluated the impact of aerobic exposure time (ET) and microbial inoculants (MI) on the fermentative and microbiological characteristics and the nutritional value of relocated whole-plant corn silage (WPCS).

The current study evaluated the relocation effect on whole‐plant corn silage (WPCS), inoculated or not, on fermentation profile, aerobic stability (AS), nutrient digestibility, and lamb's performance. Corn was ensiled in 40 experimental silos (210 L) using a completely randomised design. Silos were stored for 90 day and the treatments were: silage without inoculants (WI) and without relocation (SISR), WI silage and relocation (SIR), silage inoculated with Lentilactobacillus buchneri and relocation (LBR), and silage inoculated with L. buchneri + Lactiplantibacillus plantarum and relocation (LBLPR). Silages were exposed to air for 24 h, repacked and stored another 90 day. Twenty‐four Santa Inês lambs (17.4 ± 2.0 kg) were used for digestibility and 36 (20.9 ± 2.0 kg) for performance assays. The SISR group had higher filamentous fungi, yeast, and lactic acid bacteria (LAB) counts. SIR had lower filamentous fungi and LAB counts and lactic acid (LA) concentrations than LBR and LBLPR. LBLPR had a higher LAB count and LA concentration than LBR. The AS and time, in h, for the maximum temperature (TM) of the silages and diets were lower in the SISR. SIR had a lower AS than LBR and LBLPR, whereas LBR had a lower AS than LBLPR. Except for non‐fibrous carbohydrates, nutrient intake was higher for SIR than SISR diets. The treatments didn't affect digestibility, nitrogen balance, or performance. The performance of lambs fed relocated WPCS was not affected when the silage was exposed for 24 h during relocation, independent of microbial inoculation.

The study aimed to evaluate the effect of creep-feeding on growth performance of beef calves and milk yield of dams, during nursing phase. The experiment lasted 170 days, from December/2021 to May/2022, the calves were born in September/2021 and creep-feeding supplementation started from approximately 70 days of life until weaning. The experimental design used was a randomized block [blocked by body weight (BW) of calves]. The experimental units were the paddocks (8 units per treatment, and ten replicates per paddock), totalling 156 pairs cow/calf (86 pairs of male calves and 70 pairs of female calves). The treatments consisted of creep-feeding or not creep-feeding the calves: control treatment (CONT; mineral supplement ad libitum) and creep-feeding treatment (CREEP; energetic protein supplement; 5 g/kg of BW· animal^-1· /day^-1). There was mineral supplement ad libitum for all the dams. The pairs cow/calf were kept in an area of Urochloa brizantha cv. Marandu. The data were analyzed using the SAS PROC MIXED. Male calves subjected to CONT showed less BW (-15 kg) at weaning and decreased average daily gain (ADG; -100g/day) until weaning (P < 0.01; Figure 1), while female calves showed no difference in BW and ADG (P > 0.12; Figure 2). The dams did not show difference in milk yield until weaning (P > 0.27) for male and female calves (Figure 3). This difference in results related to gender is explained by the fact that there are differences in the performance of males and females, mainly due to hormonal issues. Usually, females are born lighter than males and tend to have decreased performance throughout the whole production cycle. For milk yield and performance of dams, our results agree with what is found in the literature. There are some studies which also evaluated milk production of dams when the offspring were creep-fed, and found similar milk yield for those whose offspring received supplement in relation to those who did not receive it. This is likely because calves prefer milk, supplement, and forage, in that order, so it seems unlikely that calves would replace milk with supplements. And these results show us that the difference in the BW at weaning of males was caused by the creep-feeding supplementation.
